INSULATED JOINT FOR RAILROAD-RAIL SECTIONS.

SPECIFICATION forming part of Letters Patent No. 772,009, dated October 11, 1904. Application filed June 4, 1901. Serial No. 63,125. (No model.)

To all whont it may concern:

Be it known that I, GEORGE A. WEBER, of Stamford, county of Fairfield, State of Connecticut, have invented a new and useful Im- Further objects of the invention are to secure a firm splice between the rails withhigh' insulating qualities.

Further objects of the invention will hereinafter appear; and to these ends the inven tion consists of an insulated joint for carrying out the above objects embodying the features of construction, combinations of. elements, and arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings.

In the accompanying drawings, Figure 1 is a transverse section of a railroad-rail joint embodying my improvement. Fig. 2 is a top view of the same, partly in section. Fig. 3 is a transverse section of a railroad-rail joint embodying a modified form of joint. Fig. 4 is an elevation of one side of the last-named railroad-rail joint.

Similar letters of reference designate corresponding parts in all the figures.

Referring first to Figs. 1 and2, A A designate two rail-sections arranged in line end to end. B B designate two angle-chairs each having a base 6' and. an upright or boltplate 6 the two being preferably strengthened at the junction by an outside fillet or rib 6 and an inside fillet or rib b. The bases of these angle-chairs are in line and almost reach each other. The uprights of these anglechairs are on opposite sides of the rail-sections. C C designate bars or blocks of insulating material, preferably of vulcanized fiber, fitted against opposite sides of the webs of the rail-sections. Outside these bars are filling-pieces D D preferably of metal and in the form of thimbles. E is a strip of insulating material, preferably vulcanized fiber, extending entirely over the bases of the angle-chairs. Preferably it extends up to the top of the uprights of those chairs; but it may stop short of extending to the tops of the uprights, and then washers E will be arranged intermediate of the filling-pieces and the uprights of the angle-chairs. The feet of the rail-sections rest upon this strip of insulating material. Outside the uprights of the angle- .chairs are washers F of insulating material, preferably vulcanized fiber. Outside these washers are metal washers G G The angle-chairs B E the bars C C and the strip of insulating material E extend across the adjacent ends of the rail-sections A A and to a, sufficient extent to form a strong joi'nt. Bolts K secure the parts together, and they pass through the washers G G F F, uprights of the angle-chairs B B thimbles D D the bars C C and the rail-sections A A Either the rail-sections are insulated from the bolts or the uprights of the anglechairs are insulated from the bolts. Both of these insulations may, of course, be adopted. I have shown bushings L surrounding the bolts where they pass through the uprights of the angle-chairs. These bushings may advantageously extend through the washers F F G G Turning now to Figs. 3 and 4, it will be seen that the joint is the same as that already described excepting only that the angle-chairB with its appurtenances, and the thimbles D are omitted. The bolt-washers G in this modificationbear directly upon the insulating- 2 an opposite part in the form of a bolt-plate also lapping the end portions of the rail-sections is provided, for the bolt-plate of the second angle-chair in the example of the invention illustrated in Figs. 1 and 2 is an opposite part to the bolt-plate of the first anglechair.

Obviously some features of this invention may be used without others and the invention may be embodied in widely-varying forms.

Therefore, without limiting the invention to the constructions shown and described nor enumerating equivalents, I claim, and desire to secure by Letters Patent, the following:

1. .The combination with adjacent rail-sections arranged end to end, of an angle-chair having a base and an upright or bolt-plate and lapping the end portions of the rail-sections, a bar of insulating material arranged intermediate the rail-sections and said upright and adjacent to the sides of the webs of said rail-sections, metal filling-pieces between the upright of the angle-chair and the adjacent bar of insulating material, a part in the form of a bolt-plate opposite the upright of the angle-chair arranged on the other side of the rail-sections, and bolts forsecuring the parts together.

2. The combination with adjacent rail-sections arranged end to end, of bars of insulating material arranged upon opposite sides of the webs of the rail-sections, an angle-chair having a base and an upright or bolt-plate and lapping the end portions of the rail-sections, metal filling-pieces between the upright of the angle-chair and the adjacent bar of insulating material, a part in the form of a boltplate opposite the upright of the angle-chair arranged on the other side of the rail-sections, and bolts for securing the parts together.

3. The combination with adjacent rail-sections arranged end to end, of bars of insulating material arranged upon opposite sides of the webs of the rail-sections, two opposite angle-chairs, each having a base and an upright or bolt-plate, and both lapping the end portions of the rail-sections, metal filling-pieces between the uprights of the angle-chairs and the bars of insulating material, and bolts for securing the parts together.

4. An insulated rail-joint, comprising the rail ends, bars of insulating material arranged along the rail-webs at each side, a bolt-plate at one side of the joint, filling-pieces in the form of thimbles on the bolts and arranged between the bolt-plate and one of the said insulating-bars, and suitable insulation for preventing the electric continuity of the rails.

5. An insulated rail-joint, comprising the rail ends, bars of insulating material arranged along the rail-webs at each side, a rail-chair having a base and an upright or bolt-plate, filling-pieces in the form of thimbles on the bolts and arranged between the upright of the chair and one of the insulating-bars, and suitable insulation for preventing the electric continuity of the rails.

6. An insulated rail-joint, comprising the rails, an angle-chair having a base and an upright or bolt-plate, a bar of insulating material arranged intermediate the rails and said upright, metallic filling means between the upright of the chair and the adjacent bar of insulating material, and a part opposite the upright of the angle-chair on the other side of the rails, with bolts for securing the parts together, and suitable insulation for preventing the electric continuity of the rails.

7. An insulated rail-joint, comprising the rails, bars of insulating material arranged upon opposite sides of the webs of the railsections, an angle-chair having a base and an upright or bolt-plate, metallic filling means between the upright of the angle-chair and the adjacent bar of insulating material, a part opposite the upright of the angle-chair arranged on the other side of the rail-sections, bolts for securing the parts together, and suitable insulation for breaking the electric continuity of the rails.

8. An insulated rail-joint, comprising the rails, bars of insulating material arranged upon opposite sides of the webs of the railsections, two opposite angle-chairs each having a base and an upright or bolt-plate, metallic filling means between the uprights of the angle-chairs and the bars of insulating material, bolts for securing the parts together, and suitable insulation for preventing electric communication between the rails.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE A. WEBER.
